Get familiar with the site then do a search for question. :<)

 

+1, all he has to do is a simple search of this forum and he would have seen the section relating to exhaust issues.

 

change the header out or cut the cat out of the stock header, that will help the sound.

 

V&H slip on's usually has a tiny sound as I call it. After some carbon builds up inside it will change some.
If your after deep sound on a low cost I would consider rush slip on's.
There are others that sound good to. Do some research on utube and listen to clips. Better yet go to a bike hang out and have a listen
